In the past few years, many B2B teams going overseas have been frantically adding LinkedIn friends, and even regard "how many people have been added" as a core indicator. But starting in 2025, more and more teams have discovered that the effect of the same operation is declining: the connection pass rate is lowered, private message replies are fewer, and the conversion cycle is longer.

It’s not that LinkedIn is no longer easy to use, it’s that the environment has changed. The platform is more crowded, users are more cautious, and competition is fiercer. In this case, it is difficult to get through extensive additions. What really determines the efficiency is who you add and whether you have a second access channel.

In other words, mature contacts + valid email are becoming the new basic configuration.

A clear change in the European market: connection does not equal communication

In the European market, LinkedIn's user structure is relatively mature, and many users are accustomed to being exploited. The result is:

  • The connection is passed, but the private message is not read
  • I read the private message but didn’t reply
  • The response rate is obviously concentrated in a small number of people

This illustrates a problem: relying solely on LinkedIn private messages, the reach link is no longer stable enough.

Especially in manufacturing, SaaS, trading and other industries, more and more teams are beginning to use LinkedIn as the "entry" rather than the only communication tool.

Why “Mature Contacts” Are Increasingly Important

In the current environment, not all contacts are worth adding.

Mature contacts usually have several characteristics:

  • Position matching (decision maker or key position)
  • The company has clear business needs
  • The account has real usage behavior

Compared with Pan-Canadian users, the number of such contacts is smaller, but it is easier for actual communication to occur.

If there is no filtering, a typical problem will arise: a lot of people are added, but there are very few really valuable conversations.

Email is becoming a key access channel again

As the efficiency of LinkedIn private messages declines, the importance of email is rising.

The reason is very practical:

  • Email does not depend on platform algorithm
  • The communication link is longer and can be followed up continuously
  • More suitable for B2B complex decision-making process

In the European market, many business users are more accustomed to handling business communications through email rather than instant messaging tools.

Therefore, an effective development path is usually:

Establish a connection on LinkedIn → Get an email → Continue to follow up via email

Rather than staying within LinkedIn.

Why mailbox data must be filtered

Although many teams are aware of the importance of email, if they use it directly after obtaining it, the results are still unstable.

The reason is that there is a problem with the mailbox data itself:

  • Invalid email or wrong address
  • Emails that have not been used for a long time
  • Contacts that do not match the target industry

Failure to filter will result in:

The sending volume increases, but the effective reach does not increase

The bounce rate is high, which affects the overall sending ability.

The response rate fluctuates greatly and is difficult to optimize

Therefore, mailbox data also needs to be treated like numbers.

A more efficient LinkedIn development process

In the current environment, a more stable approach is to combine "adding people" and "data processing" rather than executing them separately.

You can follow this logic:

Filter target contacts (position + company)

Establish a LinkedIn connection

Get mailbox data synchronously

Check the validity of your email

Use stratified by quality

In this way, development can be transformed from "single-point touch" to "multi-channel touch".

The practical effect of using Amman to improve data quality

In the processing of email and number data, Amman can complete:

  • Check email validity in batches
  • Filter active or available contacts
  • Output hierarchical label data

This can avoid putting a large number of invalid email addresses into use, and at the same time allow high-quality contacts to enter the contact process first.

In actual operation, you can first obtain contacts through LinkedIn, and then use Amman to process the email data, making subsequent communication more stable.

After the data is layered, the contact methods need to be adjusted simultaneously.

After the screening is completed, the contact methods must also be distinguished.

High quality contacts

Prioritize personalized emails or in-depth communication

Medium quality contacts

Test with standardized email templates

Low quality contacts

Reduce investment to avoid affecting overall performance

This approach allows resources to be focused on more valuable groups of people.

European B2B development is moving from “adding people” to “screening people”

The current trend is obvious: it is not whoever adds more who wins, but whoever screens accurately and who is more efficient.

As the platform environment changes, LinkedIn is only the first step. The real competition lies in:

Can you identify mature contacts

Do you have mailbox data available?

Can you turn data into ongoing communications?

When these three points are connected, development efficiency will be significantly improved, instead of relying on a single platform to try again and again.

Amman is the world's leading number screening platform, providing global customers with batch number screening and testing services covering 236 countries. The platform currently supports more than 40 mainstream social networking and applications, including WhatsApp, Line, Twitter, Facebook, Instagram, LinkedIn, Viber, Zalo, Binance, Signal, etc., adapting to the needs of multiple scenarios.

The main core functions cover multi-dimensional precise screening such as activation, activity, interaction, gender, avatar, age, online, accuracy, empty account, mobile phone device, etc., and can flexibly meet the needs of different users. Its core advantage is to integrate global mainstream social and application resources to provide users with one-stop, real-time and efficient number precision screening services, helping customers achieve global digital layout.

It is a common choice for all professional teams to complete rational screening before actually reaching users.
